It's important to keep apples to apples as threads like this often contain advice that work for residential properties, but won't work in the commercial arena.
Super creative financing "can" work once in a great while, but it's not the norm. I know that's not what you want to hear, but it's better that you do. I've done this for too long and have seen an ocean of people try to start their real estate career based on hail Mary's.
Banks aren't stupid and can see right through what people are trying to do so they'll know if you're trying to cobble a deal together. They're going to look at the source of the down payment to see if the funds are yours or if they're borrowed. They're going to look at your experience to see if you are a capable borrower. Granted, this component can be mitigated to a point by bringing in an experienced partner or by using a reputable PM, but the point is a bank can, and will, see the big picture.
You NEED to have your own funds into the deal for this to have a measurable chance of success. You need to have multifamily experience. If not, find a partner who does or find a good PM. Get those lined and work out the details first.
